I reassembled the Sony SLV-660HV after clearing a tape problem now the tape unit will not load and I get a error code of E4 01 15. Does anyone have an idea of what that code means. The unit actually tries to load but then it ejects. Thanks for any help.

Re: SLV-660HV Will not load
If you removed the tape carriage assembly, gear timing is probably off, assuming it is gear driven. Being one tooth off will prevent things from working properly. Gears will often have a mark (like an arrow or dot) which must be lined up with each other, in a mode specified in manufacturer service literature.
Another possibility is sensors. There are sensors (usually optical) which tell the logic when the tape is properly loaded. If one of these is broken, or otherwise non-functional, logic circuitry will go into error mode, and, in this case, eject tape & display an error code.
Lastly, check your mode switch. This tells the logic what position the mechanicals are in (gears/levers/slides). Again, if this is awry, you will have an error condition.

First you must make sure you got all of the video tape out of the unit. Unplug your unit from power and check for any remaining tape. Any small piece of tape could jam your unit and give you error code E3. Once you know you removed all tape leave your unit unplugged for 5 minutes to see if it clears up the error code. E3 is a drum rotation error code and usually clears after plugging the unit back into the power. If this did not help then further repair will be necessary.
While the tape may appear to be loading properly, it is not. These units have a known problem with the grease at the loading arm getting sticky. This means that the tape is not loaded properly and will not move through the VCR properly. This is detected as the hubs not moving and the unit will eject the tape to prevent damage. This is a simple repair for anyone that has done these before, but requires an alignment check. This check requires a special alignment tape and equipment.
There is a threading arm that has gummed up inside the unit. I suspect that the tape is not being loaded correctly. This is a common problem with the Sony units and requires the removal of that loading arm to remove gummed up grease. Once that is completed, the unit will function correctly. Please note that the height of this swing arm is critical to the correct loading of the tape. I would not suggest you attempt this repair because the tape height adjustment needs to be exact. A local shop should be able to resolve this for you with NO parts required.
I had a similar problem with a Panasonic VCR. It would not eject the tape and gave an error code. I found that the door does not quite fully open, so that the top of the tape hits the door and cannot eject. If I turn off and then turn on the VCR the error code disappears. Then I press the eject button and simultaneously hold the door fully open with one finger until the tape starts to eject and clears the door.
Is it having trouble either loading or ejecting the tape? If so, then something is probably awry in that mechanism. Take the top cover off and watch a load or eject operation. If tape isn't fully loaded, and tape threaded, then an error condition will result, as will be the case if it won't eject.
Causes include a broken piece of the load mechanism (also called cassette carriage or carriage mechanism), broken or cracked gear. If the mechanism is gear driven, timing is critical, just being out of time one tooth will foul things up. There are often marks on the gears which must line up exactly in a particular mode as specified in manufacturer service literature.
Most VCRs since the early '90s are disposeable, very prone to breakage, in contrast to early units which were made like tanks, costing $400 plus.
